Hello . Is everything OK ? Can I help you ?   Oh , wonderful ! You speak English ! I need to exchange this foreign currency .   That's no problem . Is it cash ?   It's Traveller's Cheques , is that possible ?   Of course . If you could sign your name on the bottom line here , and write your address here . And please sign and date the back of every cheque and of course I'll need to see your passport .   Yes , right , certainly . Here you go .
